it going with the flow of traffic, doing what people expect you to do, etc.
A guy weaving through traffic is very dangerous, trying to do 75 mph when traffic is flowing at 35 mph. We have plenty of people trying to do that here. But, it's also dangerous for some one to going 50 mph when the traffic is flowing at 65 mph -- and we also have plenty of them here.
If speed kills, then most fatal accidents would occur on the highway. This isn't true; for example, when I was studying up on the autobahn before going over to Germany one source claimed that, IIRC, less than 12% of all traffic accidents occured on the autobahn.
And, one reason is that the vast majority of German drivers act predictably (both on the autobahn and city streets -- I drove over 3000 km plus was a passenger too). For example, I only saw 1 person weaving through traffic, and I'm not sure he was German (driving a Lexus, very rare in Germany, so might have been an American). I'd say the majority were also much better, crisper drivers than the average here. Now Spain, that's a different matter....
So, yes, speeding can be dangerous....for example, mixed with alcohol, drag racing on city streets (e.g. Charlotte Hornet basketball player who crashed his Porsche at 100+ mph), weaving through traffic, etc. But, in the middle of Texas on a deserted interstate that goes straight for hundreds of miles, 100+ mph can be very safe.
I'd like to see more tickets based on unsafe driving and fewer based on exceeding an arbitrary number -- if it could be done reasonably objectively.
